4 Claims. (Cl. 156-14) The present invention relates to window screensand has for its object to provide a simple form of screen which can be readily secured in position under proper tension and when removed may be rolled up compactly about the frame members for safe storage.

A further object is to provide an improved frame member combining therein a face plate and a rearwardly extending flange, the said face plate having bearing surfaces above and below the flange with means to secure one edge of the screen fabric to the inner face of one of said bear-- ing surfaces with the other bearingsurface in position to make contact with the outer sash guide of the window frame, with the inwardly extending flange in position to be engaged by the locking devices to hold the frame member with the screen thereto attached in proper position.

A further object is to so construct the frame member that it may be employed if desired in forming a rectangular screen frame having appropriately mortised joints and to make it possible to cut a frame member on an angular line so as to match the angular end of an adjacent frame'member withput the necessity of reversing the material so as to produce reversed angular ends on the same frame member. v

A further .object is to provide a simple mechanical connection, union or joint, between the angular ends of adjacent frame members in the formation of a rectangular frame.

Qther objects will appear in connection with the following description of the invention. I v

The invention is illustrated in the accompanying drawing in which- Fig. 1 shows a broken vertical cross-sectional view on the line |-l in Fig. 2, extending through a window frame with one form of the window screen in position therein;

Fig. 2 shows a broken view of a window frame with the screen shown in Fig. l in position showing the inner face thereof; Fig. 3'is a fragmentary detail, a portion of the window frame being shown in section on the line 3-3 in Fig. 4, and showing a plan view of the inwardly projecting flange and one of the tension-applying locking devices therefor;

Fig. 4 is a fragmentary view partially in section taken on the line 4-4 in Fig. 3 and at right angles to Fig. 3; I

Fig. 5 is a fragmentary perspective view showing a portion of one of the frame members secured to one end of the screen material;

Fig. 6 is a fragmentary view showing the rear face of a corner of a rectangular screen frame with the screen material connected to the adjacent frame members, the angular ends of. which I have been secured together and comprising a screen with a rectangular frame.

Similar reference characters will be employed 5 to designate corresponding parts.

In the drawing l represents a window frame of the usual and ordinary construction supporting the usual upper sash 2 and lower sash 3. As usual in such frames, there are suitable guides 10 4 and 5 forming the guide channels 6 and I in which the sash members 2 and 3 are guided in their sliding movement. At the bottom there is provided the usual sill member 8.

In the form of my invention shown in Figs. 1 1 5 to 5, a strip of screen-material 9 is provided at its upper and lower ends with the frame members 10. Each of the frame members It is made of the channels l3, the said flange l4 being of substantial width so as to make contacts with the 30 opposed outer face of the guide members 5 at the top and bottom-of the frame I. The flanges I, when used as shown in Figs. 1 to 5, are cut away at their opposite ends as shown at l5, leaving the front member of the frame extending lateral- 35 ly at each end of the flange I 4 in order that the inner face I! of the members ill at the top and bottom of the screen above and below the flange l4 may firmly bear against the outer face of the sash frame 5 at or near each end thereof, and

entirely contact with the outer face of the sash frame 5 at each end. a I

The screen material 9 is permanently connected to the inner face I! of the member I 0 by means of a metallic rod l6 which is laid upon the marginal edge of the fabric and forced into the groove. l3 wedging the fabric and rod into the channel I3 at one side of the flange -l4. As the portion l 0 of the frame member is provided with grooves 5 along both sides of the flange I 4, it is obvious that a section of he frame member may be connected to either end of the screen fabric 9 without the necessity of adjusting the frame member sectionsas would be necessary if but a single groove At or near the ends, the flanges It are provided with'openings I! by means of which the frame members are connected to the attaching means as, for instance, threadedscrews II at the top,

the heads of which pass through the slots l1 and are engaged by latch plates It, said latch plates being pivoted as at 20, all as shown in Figs. 1 and 2 of the drawing. I

The'frame member 5 at the bottom adjacent the sill 8 will be provided with metal plates 2| having threaded sockets 22 in which a threaded stud 23 is adjustably mounted. The threaded stud 23 at its upper end isprovided with an open hook 24, constituting bearings for the latching cam levers 25, each of which is slotted at 26 to receive the upper hooked end of the stud and also carrying a pintle 21 to detachably connect the lever with the hooked end of the stud. )I'he .lever will preferably be provided with an extended end or handle 28, by means of which the.

cam portion of the lever 25 may be locked while in engagement with the upper surface of the flange It, thus applying tension thereto and to the screen fabric and looking it in position, all as shown in Figs. 1, 2, 3, and 4 of the drawing.

In Fig. 6 the frame-forming metal molding or material is shown mortised at the corners, as at 29, with the screen material 9 having its ends and side edges 30 and 30' secured in the grooves at one side of the flange l4. v'I'he outer grooves 3|, in this form of frame, receive an angular materialand upon the other side of the flange I provide aflrm bearing against the sash guide 5 of the window frame I.

In this form of the invention any suitable detachable fastening means. such as those shown and described, may be employed to connect the.
